An Algorithm for the Selection of Physical System Model Order Based on Desired State Accuracy and Computational Efficiency
(American Society of Mechanical Engineers (ASME), 2003)
In recent years, algorithms have been developed to help automate the production of dynamic system models, The focus of this development has been to create procedures and algorithms that use modeling metrics for generating ...
A modular modeling approach for the design of reconfigurable machine tools
(Affiliation: Department of Mechanical Engineering, University of Michigan, Ann Arbor, United StatesAffiliation: Department of Mechanical and Manufacturing Engineering, University of Cyprus, CyprusCorrespondence Address: Ersal, T.Department of Mechanical Engineering, University of Michigan, Ann Arbor, MI, United Statesemail: tersal@umich.edu, 2004)
A new generation of machine tools called Reconfigurable Machine Tools (RMTs) is emerging as a means for industry to be more competitive in a market that experiences frequent changes in demand. New methodologies and tools ...
Thixotropy of semisolid metals
(Materials Research Society, 2000)
Understanding the time-dependent flow behavior of metal alloys in semisolid state is essential for the further development of the process. In the present investigation, the thixotropic behavior of semisolid slurries is ...
Model reduction of modal representations
(American Society of Mechanical Engineers (ASME), 2006)
Dynamic analysis is extensively used to study the behavior of continuous and lumped parameter linear systems. In addition to the physical space, analyses can also be performed in the modal space where useful frequency ...
Transient flow characteristics and properties of semi-solid aluminum alloy A356
(Affiliation: Advance Casting Research Center, Metal Processing Institute, WPI, Worcester, MA 01609, United StatesAffiliation: Department of Mechanical and Industrial Engineering, University of Cyprus, P.O. Box 20537, 1678 Nicosia, CyprusCorrespondence Address: Tonmukayakul, N.Advance Casting Research Center, Metal Processing Institute, WPI, Worcester, MA 01609, United States, 2004)
Development of numerical models to simulate flow characteristics of semi-solid metals in the die cavity requires a good understanding of the transient and equilibrium flow properties of semi-solids and knowledge of the ...
Time-dependent rheology of semisolid metal suspensions
(Affiliation: Metals Processing Inst, Worcester, United StatesCorrespondence Address: Burgos, Gilmer R.Metals Processing Inst, Worcester, United States, 1999)
Understanding the time-dependent flow behavior of semisolid materials (SSM) is essential for the simulation of semisolid processes. During processing, the structure of the material changes with the processing history due ...
3-D flow of Herschel-Bulkley fluids
(ASME, 1998)
The flow of Herschel-Bulkley fluids through a sudden 3-D square with expansion height ratio of 2:1 is studied numerically by solving the mass and momentum conservation equations along with a continuous constitutive relation. ...
Mechanical stress regulates tissue oxygenation, cancer cell proliferation and drug delivery during progression of solid tumors
(Springer Verlag, 2016)
Oxygen supply plays a central role in cancer cell proliferation. While vascular density increases at the early stages of carcinogenesis, mechanical solid stresses developed during growth compress tumor blood vessels and, ...
Maximum likelihood diagnosis in partially observable finite state machines
(2005)
In this paper we develop a probabilistic approach for fault diagnosis in deterministic finite state machines (FSMs). The proposed approach determines whether the FSM under consideration is faulty or not by observing (part ...
NUMERICAL ANALYSIS OF ANCIENT MULTI-DRUM COLUMNS WITH EPISTYLES UNDER DYNAMIC LOADINGS
(International Association for Earthquake Engineering, 2008)
In this research work, the Discrete Element Methods (DEM) is utilized to investigate the response of ancient multi-drum columns during harmonic and earthquake excitations by simulating the individual rock blocks as distinct ...
